robotics/403af7af_9361.txt | For as long as they have existed, air bearings have primarily occupied a peculiar design space-part curiosity, part revolutionary, and often difficult to manufacture, the air bearing's incredible potential has been recognized for centuries. |
robotics/5116_2e518938aacdf0fd_44.txt | The V120:Trio camera from Optitrack is placed at about 60 cm of one extremity of the duct so at least two cameras can track the drone and the duct. The selection of this camera is based on its millimeter-level precision in tracking small objects like drones, as demonstrated in ref. 58, 1267–1274 (IEEE, 2024)."). The ca... |
robotics/73a15c41_7842.txt | Hi Jan, Is there such a thing as a hybrid servo that just responds continuously to incremental steps of 180 and doesn't track it's absolute rotation? I have an application for a gimbal where I can close the loop outside the servo and doesn't require absolute accuracy or precision over multiple revolutions? Each 360 ... |
robotics/1211_fe650460e2acb790_446.txt | Generation of autonomous behavior for robots is a general unsolved problem. Users perceive robots as repetitive tools that do not respond to dynamic situations. This research deals with the generation of natural behaviors in assistive service robots for dynamic domestic environments, particularly, a motivational-orient... |
robotics/14178_d4eee9ddd5e6add2_323.txt | is the probability of measuring z t given the known map M and assuming that the robot takes the observation at location x t . We encourage the reader to take a moment to review these concepts in section 5.6.5. In the next sections, we will describe the three main paradigms developed over the last two decades to solve t... |
robotics/d859864e_8625.txt | A geometric rotation transforms lines to lines, and preserves ratios of distances between points. From these properties it can be shown that a rotation is a linear transformation of the vectors, and thus can be written in matrix form, Qp. The fact that a rotation preserves, not just ratios, but distances themselves, is... |

The pushbutton from the previous breadboard drawing has been rearranged, and new buttons have been added, as follows. The pushbuttons straddle the center divide of the breadboard in rows 4-6, 9-11, 14-16, 19-21, and 24-26, respectively. 10-kiloh... |
robotics/8895_80ceca0747858829_90.txt | Water fountains have long served as essential providers of drinking water in public places , whether that be in school or in a shopping mall. Though companies often assert that these fountains are clean and equipped with antimicrobial features to inhibit bacteria growth, doubts still persist about the validity of such ... |

The treble is considerably more forward on the Aeon and comes across as hotter when comparing to the warmer darker sound of the Cascade. These two are so different that it is hard to draw compar... |

robotics/1266_e26caa74eb27f4da_136.txt | The potential of large language models (LLMs) as decision support tools is increasingly being explored in fields such as business, engineering, and medicine, which often face challenging tasks of *decision-making under uncertainty*. In this paper, we show that directly prompting LLMs on these types of decision-making p... |
robotics/1266_e26caa74eb27f4da_35.txt | Large language models continually learn through the accumulation of gradient-based updates, but how individual pieces of new information affect existing knowledge, leading to both beneficial generalization and problematic hallucination, remains poorly understood. We demonstrate that when learning new information, LLMs ... |
